  The flat intermediate region 100c of the slide door 100 has a bulging portion 3g in which the resin flowing from the gate when the slide door main body 100a is injection-molded is solidified at the depression of the molding die. And these protrusion part 3 and bulging part 3g are the same directions (from the back of the paper surface of FIG. 1) as the 1st sliding part 1a, the 2nd sliding part 1b, the 1st drive part 2a, and the 2nd drive part 2b. It projects from the surface of the slide door body 100a in the direction toward the front side.

  Next, the cross-sectional shape of each part shown in FIG. 2 will be described. FIG. 3 is an enlarged cross-sectional view taken along line S3-S3 in FIG. As shown in FIG. 3, the first sliding part 1a (the same as the second sliding part 1b not visible in FIG. 1) and the first driving part 2a (second driving part 2b) composed of a gear part are a sliding door. The resin 100 is integrally molded with the main body 100a, and the opposite side where the hollow recesses 1a1 and 2a1 are formed protrudes upward in FIG.

  Next, FIG. 6 is an enlarged cross-sectional view taken along line S6-S6 in FIG. As shown in FIG. 6, the bulging portion 3 g provided in the intermediate region 100 c on the plane of the slide door 100 protrudes upward in FIG. 6, that is, on the front side of the slide door 100, like the other protrusions. Therefore, there is no protrusion on the back side of the slide door 100, and the back side forms a flat surface.

  Further, as can be seen from FIG. 2, both end portions in the second direction, which is the direction in which the slide door main body 100 a slides, have rebound portions 5 a and 5 b that rebound toward the front side of the slide door 100, similar to the protruding portions. This increases the rigidity of the thin sliding door 100.

  Next, FIG. 7 is an enlarged plan view of the connecting gear 2a5 or 2b5 provided at the end of the first drive unit 2a and the second drive unit 2b of FIGS. The connecting gears 2a5 and 2b5 are part of the first drive unit 2a and the second drive unit 2b. As can be seen from FIG. 7, a total of six ribs 2a51, 2b51 are also provided in each of the first gear 2a and the connecting gears 2a5, 2b5 which are part of the second driver 2b.

  Further, FIG. 8 is a perspective view of the door deformation preventing projection 3c and the boss 3a representing the protrusions 3a to 3f. As shown in FIGS. 1 and 8, the door deformation preventing projection 3c (3d to 3f is the same) is curved or inclined with little resistance to the wind flowing along the creeping surface of the slide door main body 100a from the central direction of the intermediate region 100c. It has the U-shaped plane part 3cU which has the part 3t. Further, the robot chuck boss 3a (the same applies to 3b) includes a portion protruding like a box as shown in FIG. 8B. A hole 3ah is formed in the center of the boss 3a (3b).

  The protrusion height H (FIGS. 2 and 8) of the protrusion 3 (or 3a to 3f) is formed to be substantially the same as the protrusion heights of the first drive part 2a and the second drive part 2b constituting the gear. . Further, the door deformation preventing projections 3 c to 3 f are provided particularly at the moving direction end of the slide door 100, have a convex shape toward the center of the slide door, and are formed integrally with the slide door 100. The door deformation preventing projections 3c to 3f are formed by cutting the tip of an unillustrated die extrusion pin into a semicircular shape, and pouring resin at the time of injection molding into the cut portion.

  For automatic assembly, a robot chuck boss 3a (3b is also used) used as a robot gripping part is provided in the intermediate region of the slide door main body 100a, and the first drive unit 2a and the second drive unit 2b. The protrusion height H is substantially the same as the height H.

  Next, a state in which the slide door 100 is mounted in the vehicle air conditioner will be described. FIG. 9 is an assembly configuration diagram of the slide door of the first embodiment schematically showing the inside of the air conditioning duct of the vehicle air conditioner to which the slide door is attached.

  9, a sliding door 100 is provided in an air conditioning duct 21 of a vehicle air conditioner via an attachment member 22 so as to be slidable in the vertical direction of FIG. The sliding door 100 is provided with door deformation preventing projections 3d and 3f. For the sake of simplification, the other protrusions 3 are omitted. The blower causes the wind 23 to pass through the evaporator 24 to become the cool air 25, and the cool air 25 passes through the opening 21 a in the air conditioning duct 21. A part of the cold air 25 passes through the heater core 26 and becomes hot air 27.

  The cool air 25 and the warm air 27 are mixed by the air mix unit 28 and become the conditioned air 29 blown out into the passenger compartment. In this case, the slide door 100 forms an air mix door and adjusts the mixing ratio of the cold air 25 and the hot air 27 according to the amount of sliding.

  FIG. 10 is a schematic explanatory view showing the relationship between the sliding door 100 and the opening 21a serving as a space through which the wind in the air conditioning duct 21 flows, as viewed from the direction of the arrow Y10 in FIG. The cool air 25 that tries to pass through the opening 21 a blocked by the slide door 100 flows on the surface of the slide door 100.

  At this time, since the door deformation preventing projections 3c and 3d are formed in a U-shape or streamline shape (or a convex shape at the center of the door), an increase in wind flow resistance is suppressed. In addition, an increase in pressure loss and abnormal noise can be suppressed.

  Further, the first sliding portion 1a, the second sliding portion 1b, the first driving portion 2a, the second driving portion 2b, and the protruding portions 3a to 3f (generically also referred to as the protruding portion 3) are arranged upstream of the air. Although it has a convex shape, it is scattered in the vertical direction of FIG. 1 along the air flow to reduce wind resistance.

Further, the sliding door 100 is a door that seals wind pressure, and the movement direction end having a large influence on the performance is prevented from being deformed by the door deformation preventing projections 3c, 3d, 3e, and 3f. Disappears.
(Operational effects of the first embodiment)
FIG. 11 is a front view showing a state in which a large number of slide doors 100 according to the first embodiment are stacked. According to this, in the case where a large number of slide door bodies 100a made of resin-molded thin plates are stacked and transported, the first sliding portion 1a and the first sliding portion are respectively provided at both ends between the stacked slide doors 100. The two sliding portions 1b, the first driving portion 2a, and the second driving portion 2b are provided in a protruding shape, so that a gap between the stacked sliding doors 100 can be secured.

  Further, in the middle region 100c of the slide door 100, the first sliding portion 1a, the second sliding portion 1b, the first driving portion 2a, and the protruding portion 3a to the protruding portion 3a having at least the same height as the second driving portion 2b. 3f (generally referred to as the protruding portion 3), the protruding portion 3 can shorten the length of the flat portion of the slide door body 100a that is not held, and the stacked sliding doors 100 are stacked. It is possible to suppress the sagging of the intermediate region 100c between each other. Thereby, the deformation | transformation during conveyance of the slide door 100 can be suppressed.

  In addition, since one of the protrusions 3 includes bosses 3a and 3b for robot chuck, the bosses 3a and 3b necessary for the robot to grip the slide door 100 are allowed to hang down when the slide door 100 is stacked. It can be utilized as a support between the sliding doors 100 to be prevented.

  Furthermore, the other part of the protrusion 3 is provided at the end (moving direction end) in the second direction (vertical direction in FIG. 1) perpendicular to the first direction (left-right direction in FIG. 1) of the slide door body 100a. The door deformation preventing projections 3c to 3f are formed. Therefore, when the slide doors 100 are stacked, the door deformation preventing projections 3c, 3e, 3d, and 3f that are opposed to each other can be used as supports between the slide doors that prevent the slide doors 100 from hanging down.

  In addition, this protrusion part 3 may be provided opposite to the both ends of a 2nd direction (left-right direction of FIG. 1). However, as shown in FIG. 1, by providing the door deformation prevention protrusions 3 c to 3 f at the sliding direction end of the sliding door 100, it is possible to prevent warping of the moving direction end that greatly affects the performance.

  The door deformation preventing protrusions 3c to 3f have a curved or inclined portion with a low resistance to the wind flowing along the creeping surface of the slide door main body 100a from the center of the intermediate region (in other words, as shown in FIG. 1). When viewed from the plane direction, it exhibits a streamlined shape such as a U-shape or an inverted U-shape), so that when the slide door 100 is attached to the vehicle air conditioner, the air-conditioning air flowing on the surface is obstructed. Can be reduced.

  The door deformation preventing projections 3c to 3f having a streamlined shape such as a U-shape or an inverted U-shape are cylindrical push pins (also referred to as protruding pins or ejector pins) (not shown) of the resin molding die. It is formed by cutting the side surface of the tip into the shape of each door deformation preventing projection 3c-3f.

  This facilitates mold release work. The reason for this is that the mold has recesses for forming the respective door deformation preventing projections 3c to 3f recessed inside the mold, and if the respective door deformation preventing projections 3c to 3f are formed, the releasability deteriorates. When the tip side surface of the columnar push pin is formed by cutting into the shape of each door deformation preventing projection 3c-3f, each formed door deformation preventing projection 3c-3f itself and its immediate neighbor are pushed by the push pin. This is because mold release becomes easy.

  As described above, by increasing the number of holding points of the sliding doors at the time of stacking, bending (deformation) of the sliding doors can be suppressed, and deterioration of performance (sealability, operating force, sliding sound) can be suppressed. Therefore, simplification of the packing material and improvement of transportation efficiency can be achieved, and transportation cost can be reduced.

  Next, due to the presence of the ribs 1a2, 2a2, etc., the adhesion between the molds increases, and the slide door 100 can always be left on one mold side during mold release after molding, and the slide at the time of mold release Since the crack of the door main body 100a can be suppressed and the presence of the ribs 1a2, 2a2, etc. can resist the force applied in the longitudinal direction of the ribs 1a2, 2a2, etc. during lamination, the projecting portion 3, the first Any deformation of the sliding part 1a, the second sliding part 1b, the first driving part 2a, and the second driving part 2b can be suppressed. This will be described below.

  12 to 14 show a state in which the slide door 100 is injection-molded by a mold, and FIG. 12 shows a slide door in the cavity of two molds of a fixed mold 52 and a movable mold 51 as a comparative example. FIG. 13 is a schematic cross-sectional view showing a state in which the resin forming 100 is injection-molded, and FIG. 13 shows a state in which the slide door 100 as a product is pulled when the movable mold 51 is separated from the fixed mold 52 in the comparative example. FIG. 14 is a schematic cross-sectional view of the rib RB (represented by the above-described ribs 1a2, 2a2, etc., that is, 1a2, 2a2, 2a3, 2b2, 2b3, 2a51, 2b51) as in the first embodiment. FIG. 6 is a schematic cross-sectional view showing a state of the slide door 100 that is a product when the movable mold 51 is separated from the fixed mold 52 in a state in which a) is formed.

  As shown in FIG. 12, the resin is poured into the cavity where the molds are aligned. When the mold is released, the distance between the molds is widened, and the slide door 100, which is a resin molded product, is taken out. However, since the slide door 100 is a thin wavy thin plate, as shown in FIG. When the sliding door 100 is pulled between the other molds, a crack 100CR may be formed in the sliding door 100 that has just been molded.

  On the other hand, when the rib RB is formed as in the first embodiment of FIG. 14, the slide door 100 can be attached to the mold on which the rib RB is formed and released. That is, the rib RB increases the degree of adhesion between the mold 52 and the slide door 100, and the slide door 100 is not pulled between the molds, so that a crack does not occur.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the following embodiments, the same components as those in the first embodiment described above are denoted by the same reference numerals, description thereof will be omitted, and different configurations and features will be described. FIG. 15 is an explanatory view showing a state in which the bulging portion 3g shown in FIG. 6 is formed in the first embodiment. The bulging portion 3g is formed in a runner which is a branch portion of the resin flow, and is formed by pouring resin from the gate 53.

  The bulging portion 3g does not function specially as the slide door 100 and is necessary for improving the flow of the resin at the time of molding, but the height H of the bulging portion 3g is set to the other protruding portion 3. If the height H is the same, the bulging portion 3g can also be used as a deformation preventing projection when the sliding doors 100 are stacked.

  Thus, in 2nd Embodiment, the protrusion part 3 consists of the bulging part 3g which the resin which flows in from the gate when the slide door main body 100a is injection-molded solidified in the hollow part of the molding die. According to this, it is not necessary to add and form a special protruding portion, and the deformation preventing projection can be easily formed using the bulging portion 3g formed at the portion facing the gate 53.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. In the following embodiments, the same components as those in the first embodiment described above are denoted by the same reference numerals, description thereof will be omitted, and different configurations and features will be described. 17 (a) to 17 (f) are plan views of the door deformation preventing projection and other modifications showing the fourth embodiment of the present invention.

  The form shown in FIG. 17A is formed by rounding the distal end side of the door deformation preventing projection 3e1 and providing a rib 3eR. In the form shown in FIG. 17B, a rib 3eR is provided as a solid door deformation preventing projection 3e2 having no hollow portion.

  In the form shown in FIG. 17C, a rib 3eR is provided as an umbrella-shaped door deformation preventing projection 3e3 having a hollow portion. In the form shown in FIG. 17D, a door deformation preventing projection 3e4 is formed from a set of four rod-shaped projections. In the form shown in FIG. 17E, a rib 3eR is provided as a solid umbrella-shaped door deformation preventing projection 3e5 having no hollow portion. In the form shown in FIG. 17 (f), a door deformation preventing projection 3e6 is formed from a set of three rod-shaped projections.

(Other embodiments)
Further, in the above-described embodiment, the distance in the first direction between the first drive unit 2a and the door deformation prevention projection 3c in FIG. 1, and the distance between the door deformation prevention projection 3c and the door deformation prevention projection 3d in FIG. The interval in the first direction and the interval in the first direction between the door deformation preventing projection 3d and the second drive unit 2b are set to unequal pitches due to the water holes (not shown) for cooling the molding die. However, it is desirable that the pitch be equal to suppress the deflection of the sliding door 100 during stacking.

  Furthermore, in the above-described embodiment, the number of the bosses 3a and 3b constituting the robot chuck portion may be essentially one (for example, the boss 3b may not be provided and only the boss 3a may exist). However, in order to support the slide door main body 100a in a well-balanced manner as a projection for preventing deformation when the slide doors 100 are stacked, two are arranged side by side. The positions of the bosses 3a and 3b are preferably close to the bulging portion 3g. However, since there are water holes near the bulging portion 3g that serve as a mold cooling portion, the bosses 3a and 3b are located slightly away from the bulging portion 3g. Boss 3a, 3b is provided.

  In addition, when providing the sealing member which consists of urethane resin etc. which seals an air flow in the edge part of the circumference | surroundings of the sliding door 100, the protrusion height of this sealing member is set to the 1st sliding part 1a and the 2nd sliding part 1b. The height H of the first drive unit 2a, the second drive unit 2b, etc. may be made equal. If it does in this way, a seal member can be utilized as a projection for deformation prevention at the time of lamination.

  In addition, the sliding door may be bent and attached so as to be slightly curved when assembled. Further, these deformation preventing projections are projected to the front side of the slide door 100. Therefore, although there is no deformation preventing projection on the back side of the slide door 100 and the back side forms a flat surface, some deformation preventing projections may be provided on the back side.

  Moreover, the substantially same protrusion height (H) said to this invention means the height which can support the laminated slide door so that it may not deform | transform excessively, and the sliding part 1 and the drive part 2 are the same. Means almost the same height. Specifically, the height is 0.7 to 1.3 times, preferably 0.9 to 1.1 times the height of the sliding portion 1 and the driving portion 2.
